Color changing gemstones are always popular with collectors. A while back I reported on the Leviev chameleon diamonds now comes news of a stone which has been around for a while but is poised to make its mark on the gemstone market. Modern Jeweler has a long piece on this stone which shows different colors depending on the light source used. Turkish diaspore used in jewelry since the 1970s. Now it is being sold under the name of Zultanite and higher quality versions of this stone are making their way to market. The stone shifts from varying shades of green in sunlight to a pinkish brown in incandescent light. Zultanite recently turned up at the gem show in Tuscon and there seems to be interest both from home-shopping markets and from higher-end operations. Zultanite may be a chance for those who aren’t quite ready for the high prices of chameleon diamonds or alexandrite to purchase a color-changing gemstone.
